A shot blast device for an edge part is provided to improve the precision of the shot process by automatically performing the shot process on a welding zone which has been subject to a coating treatment. A shot blast device for an edge part comprises a cabinet(10), a nozzle(20), an air-shot tank(30), a conveyer(40) and a dust collector(50) connected to the cabinet through a duct(52). The cabinet has a shot division(14) defined by a shielding plate(16). The nozzle is installed on the shot division of the cabinet to spray a shot ball toward an edge part of a product. The air shot tank is connected to the nozzle to supply the shot ball in a high pressure. An auxiliary tank(32) is installed at an upper part of the air shot tank and is opened/closed by a valve(32a). The conveyor is installed at a lower part of the cabinet to collect the shot ball sprayed through the nozzle and transfer the shot ball to the auxiliary tank.
